Air limbah rumah tangga merupakan salah satu potensi sumber pencemaran lingkungan . Berdasarkan Laporan JICA , 1995 pencemaran lingkungan di Jabodetabek adalah 80 % disebabkan oleh air limbah rumah tangga . Untuk meminimalkan pencemaran lingkungan, air limbah harus diperlakukan sebelum dibuang ke sungai . Masalah yang sering muncul dalam pengelolaan limbah domestik adalah luas lahan terbatas dan dana yang ada untuk membangun fasilitas pengolahan air limbah dan juga biaya operasional yang tinggi . Untuk mengatasi masalah tersebut, perlu pengembangan biaya rendah teknologi pengolahan air limbah dengan efisiensi penyisihan yang tinggi , mudah dioperasikan dan juga harus kompak . Sebuah teknologi kombinasi Upflow Anaerobic Sludge Blanket ( UASB ) dan aliran bawah Hanging Sponge ( DHS ) merupakan pengolahan air limbah ekonomi , mudah dioperasikan dan memiliki efisiensi penyisihan tinggi yaitu 98 % untuk BOD dan 99,8 % untuk bakteri . Namun, untuk membangun fasilitas pengolahan air limbah dengan menggunakan UASB dan teknologi DHS , perlu studi kelayakan . Makalah ini menjelaskan studi kelayakan ekonomi dan sosial dari penerapan teknologi pengolahan air limbah UASB dan DHS di Kota Bogor . Dengan perhitungan manfaat dan rasio biaya ( BCR ) , hasilnya menunjukkan bahwa BCR 2.13 . Ini berarti proyek pengolahan air limbah UASB dan DHS di Kota Bogor adalah layak. Kata kunci : air limbah rumah tangga , anaerobik selimut lumpur, studi sosial ekonom  AbstractDomestic wastewater is one of the potential sources of environment pollution. Based on the JICA Report, 1995 the environmental pollution in Jabodetabek was 80% caused by the domestic wastewater. To minimize the environmental pollution, the wastewater have to be treated before discharge to river. Problem which often emerge in management of domestic waste is the limited land area and existing fund to built a wastewater treatment facility and also the high operating cost. To overcome these problems, it needs development of low cost wastewater treatment technology with high removal efficiency, easy to operate and also should be compact. A combination technology of Upflow Anaerobic Sludge Blanket (UASB) and Downflow Hanging Sponge (DHS) represents an economic wastewater treatment, easy to operate and has high removal efficiency that is 98% for BOD and 99,8% for bacterium. However, to build the wastewater treatment facility by using the UASB and DHS technology, it needs a feasibility study. This paper explains an economic and social feasibility study of application the UASB and DHS wastewater treatment technology at Bogor City. By the calculation of benefit and cost ratio (BCR), the result shows that the BCR is 2.13. It means the UASB and DHS wastewater treatment project at Bogor City was feasible.

Anaerobic Sludge Blanket

The upflow anaerobic sludge blanket (UASB) reactor has been recognized as an important wastewater treatment technology among anaerobic treatment methods. The objective of this study was to perform literature review on the treatment of domestic sewage using the UASB reactor as the core component and identifying future areas of research. The merits of anaerobic and aerobic bioreactors are highlighted and other sewage treatment technologies are compared with UASB on the basis of performance, resource recovery potential, and cost. The comparison supports UASB as a suitable option on the basis of performance, green energy generation, minimal space requirement, and low capital, operation, and maintenance costs. The main process parameters such as temperature, hydraulic retention time (HRT), organic loading rate (OLR), pH, granulation, and mixing and their effects on the performance of UASB reactor and hydrogen production are presented for achieving optimal results. Feasible posttreatment steps are also identified for effective discharge and/or reuse of treated water.

A preliminary assessment of an application of sewerage system with Upflow Anaerobic Sludge Blanket (UASB) and Down flow Hanging Sponge (DHS) technology was conducted inNorth Bogor. The Problem which often emerge in management of domestic wastewater is the limited land area and fund to built and operate a wastewater treatment facility. To overcome such problem, it is needed to develop a cheap wastewater treatment technology with high efficiency, easy to operate and also should be compact. The combination technology of UASB and DHS is proposed as an economic wastewater treatment which  easy to handling. Therefore, to make sure that the technology is feasible or not to be built inNorth Bogor, there is need the preliminary assessment. The assessment was conducted through a survey of technical and social economic aspect. The results show that sewerage system using UASB and DHS technology is feasible. Key word: domestic wastewater, upflow anaerobik sludge blanket, downflow hanging sponge, preliminary assessment.

Anaerobic Sludge Blanket

The results of pilot experiments on municipal wastewater treatment using advanced processes are described. The most important aims of this research were to achieve reductions in energy consumption, environmental impact, quantity of stabilized sludge produced, and area necessary for plant construction. The pilot plant, which was constructed in the environs of the Senigallia (AN, Italy) municipal wastewater treatment plant, had a capacity of 500 to 2500 population equivalents (p.e.). In the most attractive system, municipal wastewaters with a low organic concentration were first treated in an upflow anaerobic sludge blanket (UASB) bioreactor with a capacity of 336 m3. Part of the effluent from this process was then conveyed to an anoxic biological fluidized bed (with a volume of 8 m3 filled with 3 m3 of quartzite sand) for pre-denitrification, and then to an aerobic fixed bed (with random plastic media and a volume of 8m3) for nitrification. It was also possible to treat the municipal wastewaters using the anaerobic fluidized bed directly, after microscreening or primary sedimentation. The research undertaken was intended to verify the reliability of these processes at ambient temperatures and with variable wastewater concentrations. The preliminary results obtained for COD, BOD, and N removal from municipal wastewaters indicate that this system is quite an attractive treatment alternative, mainly due to its low sludge production and energy consumption. These results will enable accurate design criteria to be identified for the construction of more economic treatment plants on a larger scale.

The paper evaluates and models helminth eggs removal in a combined UASB (Upflow Anaerobic Sludge Blanket) reactor - maturation pond system (one baffled and one unbaffled pond in parallel). The system is comprised of demonstration-scale units, treating actual domestic sewage from Itabira city, Brazil. The paper addresses the following points: (i) removal of helminth eggs from the wastewater in the system; (ii) comparison of the observed removal efficiency with the predictions using the Ayres et al. model; (iii) accumulation of helminth eggs in the sludge; (iv) viability of eggs in the sludge; (v) distribution of helminth species in the sludge. The removal efficiency of helminth eggs from the wastewater in both ponds was 100% for most of the time (0 counts in the final effluent). The predictions of helminth eggs removal according to the Ayres et al. model can be considered reasonable. After one year of operation, 88% of the eggs in the sludge remained viable. Helminth eggs counts in the sludge tended to decrease along the baffled pond length (from first to last compartment). The prevailing helminth species found in the sludge from both ponds was Ascaris lumbricoides.
